Silver, try googling Harry + Hewitt.
Now can we get back to airports now?
I still await your business plan. UK govt will never pay for this, but they may, against their better judgement pay for the ground access, and let these sovereign wealth funds pay for the island and the airport that sinks, sorry, stands on top of it.
How will they get their money back? What would you set PSC at to make it work? How would you woo BA, who have clearly said they won't budge? Or are we going down the 2 hub system now, in which case why go to all the expense when you could just add a runway at LGW or STN?
